The difference between a traditional vswitch and a modern vswitch Some vswitches on the market claim to have QoS Assurance. In fact, they only support single-level priority settings and do not form a loop logically. In the event of a fault, the backup link is enabled, I would like to share it with you here and hope it will be useful to you. We often mention that the traditional Ethernet switch is actually a multi-port L2 network device based on the b

Resolution of compatibility issues:Because IE and Dom are different in how modern event handlers are assigned, to ensure that the code we write is available under the IE and Dom Browser series, we can use the following code to resolve compatibility issues:var fnClick1 = function () {Aleart ("I was clicked";)}var fnClick2 = function () {Aleart ("I was also clicked";)}var odiv = document.getElementById ("Div1");if (Document.addeventlistener) {//domOdiv.

1. Modern programming style is to encapsulate the data structure and algorithm together.2, in any field, well-designed algorithms are the most effective way to solve large-scale problems.3. Data abstraction and definition of abstract data type (ADT) for modular programming.4, first has the API, then has the realization, then is the proof, finally is the data. That is: first interface after implementation, emphasis on testing.5, in order to organize da

() method is often used by some PHP frameworks to map routing addresses to anonymous callback functions. These frameworks bind an anonymous function to an Application object. You can use the $this keyword in an anonymous function to refer to the Application object, as shown in example 2-22Example 2-22 attaching the closure state using the BindTo methodNote the Addroute method. It receives a routed address (for example,/users/josh) and a callback for a route. The dispatch () method receives a cu

++14, which uses auto as a parameter (thus producing a generic lambda expression):std::vector v;....auto resetV = [v](const auto newValue) { v = newValue;};//C++14 only....resetV({1, 2, 3}); //error! can‘t deduce type for {1, 2, 3}The end result is that if you do not initialize with curly braces, the auto type deduction is consistent with the template type deduction. In this case only (with curly braces for initialization), Auto is deduced as an std:: initializer_list, but the templat

(auto) in c++14, some simple changes to the return statement will affect the result of the function's final derivation:decltype(auto) f1() { int0; … return x; // decltype(x) is int, so f1 returns int decltype(auto) f2() { int0; … return (x); // decltype((x)) is int, so f2 returns int }Note that F2 and F1 are not just different on return types, F2 returns a reference to a local variable! The consequence of this code is to cause undefined behavior, which is certainly not wha

Summary of objective Modern C ++ Item 2, inclutivemoderncFirst, we propose two basic points of view: 1. auto and template parameter type derivation have almost identical rules, so the rules summarized in Item1 are applicable to auto. 2. There is a difference between auto and template parameter type derivation. The difference is that the process for curly braces is different. Why is it different? Rule! Scotter Meyer does not know the answer. We know I

Summary of objective Modern C ++ Item 1, inclutivemoderncItem 1: Understand template type deduction. Understanding template type Derivation template The type deduced for T is dependent not just on the type of expr, but also on the form of ParamType. For T-type derivation, not only the input template expression but also the dependentParamType. ParamType is a pointer or reference type, but not a universal reference. (Universal references are described

Effective Modern C ++ translation-Clause 3: Understanding decltype Clause 3: Understand decltype Decltype is a very interesting monster. If a name or expression is provided, the decltype keyword will tell you the name or type of the expression. Generally, the results are consistent with your expectations. However, in some cases, the results produced by decltype lead you to seek answers in reference books or online Q . Let's start from the general situ

Effective Modern C ++ translation-Clause 2: Understanding auto automatic type Derivation Clause 2: Understand auto type deduction If you have read section 1 about template type derivation, you have almost all about auto type derivation. As to why auto type derivation is a template type derivation, there is only one curiosity. What is that? That is, template type derivation includes templates, functions, and parameters, while auto type inference does n

[Modern PHP] Chapter II new features of the six Zend Opcache Zend Opcache Byte-code caching is not new for PHP. We have alternative PHP Cache (APC), Eaccelerator, Ioncube, and XCache as a standalone extension, all of which can be used as our options. However, they are not available in each of the core release versions of PHP. Until now PHP 5.5.0, PHP has its own built-in bytecode cache: Zend Opcache. First, let me explain what the bytecode is and h
